Climbing rose plant named ‘ORAfantanov’

ABSTRACT

A new variety of Climbing rose suitable for garden decoration, having flowers of smoky purple magenta blend coloration.

Classification: The present invention relates to a new Rosa hybridaplant.

Variety denomination: The new plant has the varietal denomination‘ORAfantanov’.

BACKGROUND OF THE INVENTION

This invention relates to a new and distinct variety of Climbing Rose.It has as its seed parent the variety known as ‘ORApaymel’ (U.S. PlantPat. No. 14,500) and as its pollen parent the variety known as‘FRAntasia’ (U.S. Plant Pat. No. 17,518).

SUMMARY OF THE INVENTION

Among the features which distinguish the new variety from otherpresently available and commercial rose cultivars known to the inventorare the following combinations of characteristics: its very unique smokypurple magenta blend flower coloration, its large clusters with multipleflowers, its many stipitate glands on the peduncle and on the surface ofthe bud and its several small prickles on the branches and new shoots.The plant has a spreading climbing growth habit, suitable for outdoorgarden decoration.

Asexual reproduction of the new variety by budding as performed in KernCounty and Pomona, Calif., shows that the foregoing and otherdistinguishing characteristics come true to form and are established andtransmitted through succeeding asexual propagations. ‘ORAfantanov’ maybe asexually propagated by cuttings, budding and grafting. The buddingand grafting successfully occurred on the plant/rootstock Rosa hybridacv. Dr. Huey (not patented).

COMPARISON WITH PARENTS

The new rose may be distinguished from its seed parent, ‘ORApaymel’ bythe following combination of characteristics: whereas ‘ORAfantanov’bears semi-double flowers (about 13 to 16 petals) of smoky purplemagenta blend coloration, ‘ORApaymel’ bears flowers of white edged redcoloration with significantly heavier petalage (about 18 to 22 petals).The new variety is classified as a climbing rose with a spreadingclimbing growth habit with canes about 300 cm. to about 350 cm. inlength, whereas the seed parent is classified as a shrub rose with asignificantly shorter bushy to somewhat spreading and rounded growinghabit (about 108 to about 125 cm. in height).

The new variety may be distinguished from its pollen parent, ‘FRAntasia’by the following combination of characteristics: whereas ‘ORAfantanov’bears flowers of smoky purple magenta blend coloration, ‘FRAntasia’bears flowers of purple-blue coloration. The new variety is classifiedas a climbing rose with a spreading climbing growth habit with canesabout 300 cm. to about 350 cm. in length, whereas the pollen parent isclassified as a shrub rose with a significantly shorter and lessspreading very upright growing habit (about 175 to about 210 cm. inheight and about 0.7 to about 0.88 cm. spread at the widest point).

COMPARISON WITH THE CLOSEST COMMERCIALLY AVAILABLE CULTIVAR

The closest commercially available cultivar to the new variety is thepollen parent ‘FRAntasia’.

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying photograph illustrates the new variety and shows theflowering thereof from bud to full bloom depicted in color as nearlycorrect as it is possible to make in a color illustration of thecharacter. Throughout this specification, color references and/or valuesare based upon The Colour Chart of The Royal Horticultural Society(1966) except where common terms of color definition are employed.

DESCRIPTION OF THE NEW VARIETY

The following description is of 3 to 4 year-old rose plants of the newvariety grown outdoors in Pomona, Calif. in the month of July.Phenotypic expression may vary with environmental, cultural and climaticconditions, as well as differences in conditions of light and soil.

FLOWER

The new variety usually bears its flowers in clusters of three to twentyfour or more per stem. Flowers are borne in regular rounded clusters onstrong medium to long stems (about 23 to about 92 cm.). Outdoors, theplant blooms abundantly and nearly continuously during the growingseason. The flowers have a strong clove to spicy fragrance.

BUD

The peduncle is about 2.2 to about 4.5 cm. in length, of average caliper(about 0.2 to about 0.25 cm. in diameter), and usually erect. It ismoderately rough, with many stipitate glands. Peduncle color is between146C and 146D.

Before the calyx breaks, the bud is about 0.9 to about 1.5 cm. indiameter at the widest point, about 1.4 to about 2.0 cm. in length, andpointed in shape. The surface of the bud bears between 2 to 5 foliaceousappendages and many stipitate glands, usually with slender entirefoliaceous parts extending beyond the tip of the bud about ¼ or more ofits length. Bud color is between 137C and 137B sometimes lightlysuffused, especially on the side exposed to the sun, with between 187Band 187A.

The sepals are about 2.4 to about 3.5 cm. in length and about 0.7 toabout 0.9 cm. in width at the widest point. The outer surface color ofthe sepal is between 137C and 137B sometimes lightly suffused,especially on the side exposed to the sun, with between 187B and 187A.The inner surface color of the sepal is near 146D broadly bordered bynear 137A. After the sepals open, the inner surface color is oftenmoderately suffused, especially on the area exposed to the sun, withbetween 187A and 187B. The inner surface of the sepal is covered withfine wooly tomentum; sepal margins are lined with some stipitate glandsand hairs.

The receptacle of the flower is of medium length (about 0.4 to about 0.6cm.) and average in caliper (about 0.4 to about 0.6 cm. in diameter).The receptacle is moderately rounded to urn-shaped in form. Its surfaceis moderately smooth with some hairs and stipitate glands and withsomewhat thin fleshy walls. The receptacle color is between 144A and146B.

As the petals open (after the calyx breaks), the bud is about 1.3 toabout 2.1 cm. in diameter at the widest point, about 1.6 to about 2.5cm. in length, and moderately ovoid to somewhat pointed in form. Thecolor of the under surfaces of the newly opened petals is between 60Band 60A sometimes moderately blushed with between 187A and 187B. At thepoint where the petal attaches, there is a moderately large zone ofbetween 10B and 11B. The color at the base of the upper surfaces of thenewly opened petals is between 187C and 60B gradually suffusing towardthe petal edge with near 187A. At the point where the petal attaches,there is a somewhat large zone of between 12A and 9A.

BLOOM

When fully open, the bloom ranges from about 6.6 to about 9.6 cm. indiameter. Petalage is semi-double with about 13 to 16 petals and about 0to 5 petaloids irregularly arranged. When partially open, the bloom formis moderately cupped to somewhat ovoid, and the petals are looselyspiraled to somewhat cupped with petal edges somewhat reflexed outward.When fully open, the bloom form is more cupped, and the petals areloosely cupped to undulated with petal edges somewhat reflexed outwardand sometimes moderately reflexed inward.

PETALS

The substance of the petals is moderately heavy and of medium to thickthickness, with upper surfaces moderately satiny and under surfacesmatte. The petals are about 2.9 to about 4.1 cm. in length and about 2.4to about 4.0 cm. in width at the widest point. Petal margins are entire.

The outer petals are moderately obovate to somewhat ovate in shape withrounded apices.

The inner petals are broadly obovate to somewhat ovate in shape withrounded apices.

Petaloids are about 1.1 to about 1.9 cm. in length and about 0.5 toabout 0.8 cm. in width at the widest point. Petaloids are irregularlyshaped moderately subulate to somewhat obovate with rounded apices.

NEWLY OPENED FLOWER

The color at the base of the under surfaces of the outer, intermediateand inner petals is near 69B gradually suffusing toward the petal edgewith between 64B and 71B sometimes moderately blushed with between 187Band 74A to as dark as near 79A. At the point where the petal attaches,there is a large zone of between 6D and 5D. The color at the base of theupper surfaces of the outer, intermediate and inner petals is between64B and 67B gradually suffusing toward the petal edge with between 71Aand 72A sometimes edged with between 74A and 71C. At the point where thepetal attaches, there is a somewhat large zone of between 8A and 7C.

The under and upper surface colors of the petaloids are similar incoloration to the upper and under surfaces of the intermediate and innerpetals.

The general tonality of the newly opened flower is between 64B and 67Bat the base gradually suffusing toward the petal edge with between 71Aand 72A sometimes edged with between 74A and 71C.

The color at the base of the under surfaces of the outer, intermediateand inner petals is between 75D and 76B gradually suffusing toward thepetal edge with between 78B and 72B sometimes moderately blushed withbetween 72A and 74A to as dark as near 79B. At the point where the petalattaches, there is a large zone of near 5D. The color at the base of theupper surfaces of the outer, intermediate and inner petals is between80B and 67B gradually suffusing toward the petal edge with between 79Band 77A sometimes blushed with between 79A and 71C. At the point wherethe petal attaches, there is a somewhat large zone of near 8B.

The under and upper surface colors of the petaloids are similar incoloration to the upper and under surfaces of the intermediate and innerpetals.

The general tonality of the three-day-old flower is between 80B and 67Bat the base gradually suffusing toward the petal edge with between 79Band 77A sometimes blushed with between 79A and 71C.

On the spent bloom, the petals usually drop off cleanly.

In July in Pomona, Calif., blooms on the bush growing outdoors generallylast about four to five days. Cut roses from plants grown outdoors andkept at normal indoor living temperatures generally last about four tofive days.
